PLOW.

Specification of Letters Patent.

Patented April 10, 1906.

Application filed December 26, 1905. Serial No. 293,896.

To 01,7] whom it may concern.-

Be it known that we, FRANKLIN B. NIESZ and JONATHAN M. STEWART, citizensof the United States, residing at Canton, in the county of Stark andState of Ohio, have invented certain new and useful Improvements inFlows; and we do hereby declare that the following is a full, clear, andexact description of the same, reference being had to the annexeddrawings, making a part of this specification, and to the numerals ofreference marked thereon, in which- Figure 1 is a perspective view ofour improved plow. Fig. 2 is a view showing the runner andconnecting-head. Fig. 3 is a vertical longitudinal section of themoldboard and share and connecting-head. Fig. 4 is a perspective viewshowing the bottom or under side of the plow.

The present invention has relation to plows; and it consists in thedifferent parts and combination of parts hereinafter described.

The particular class of plows to which this invention applies is what isknown as doublemoldboard.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings.

In the accompanying drawings, 1 represents the beam of the plow, whichis curved downwardly and forwardly, so as to form a suitable standard 2.For the purpose of pro viding a means for attaching the moldboards 3 andthe share 4 we provide the converging flanged plate 5, which divergingflanged plate is connected to the standard 2 in any convenient andwell-known manner. The parts just above described form no particularpart of the present invention, except that they are necessary incarrying out the purpose and object hereinafter pointed out by means ofthe device hereinafter described. At the lower forward end of theflanged plate 5, and upon the under side thereof, is attached theflanged runner connecting head or block 6, which head or block isprovided with the flange 7, said flange being for the purpose ofpivotally attaching the runner 8, which runner is provided at its bottomor lower edge with the lateral flanges 9. For the purpose of holdin therunner 8 in proper relative positi on and preventing any swinging orvibrating movement of said runner the braces 10 are provided, whichbraces are connected at their top or upper ends to the convergingflanged plate 5, as best illustrated in Fig. 4. The runner members 8 arespaced a short distance from each other, and between which runnermembers is located the double-edged knife 11, which knife is adjustableup and down, and to provide for the adjustment slots 12 and 13 areformed in the runners 9. In use the ground contact-surfaces of therunner-flanges 9 are worn away unevenly, and for the purpose ofproviding a means for compensating for this uneven wear the runner 8 isso formed that its ends can be transposed, or, in other words, therunner can be easily removed by detaching the bolts 14 and 15, afterwhich the ends of the runner can be changed from time to time. Theforward ends of the runner members are pivotally attached to the flange7, so that the rear ends of the runner can be adjusted up and down byloosening the bolt 14, at which time the runner is free to turn upon thepivotal points. The knife 11 is provided with the slot 16, through whichslot the bolt 14 is passed, and when the nut of the bolt 14 is tightenedthe knife 11 will be held in proper relationship with the runner 8. Forthe purpose of assisting in holdin the rear end of the knife 11 theclamping-boat 17 is provided, by means of which the runner 8 can besnugly seated against the faces of the knife 11. For the purpose ofproviding a means for double wear, so far as the knife is concerned, itis so formed that it can be inverted, thereby providing a double-edgedknife or blade. Another object in providing the kind of adjustment forthe knife or blade described is that it can be moved up and down betweenthe runner members without changing angularity of said knife or blade asbetween said runner members and the knife or blade, respectively, bywhich adjustment no fixed pivotal connection is necessary as between therunner and knife, by which arrangement the knife or blade is adjusted upand down be tween the runner members throughout its entire length. Byproviding the adjustment for the runner and the knife or blade they canbe set in different positions as between the moldboards and to differentdepths, thereby assistingin the operation of the plow,

and thereby and at the same time cause the plow to move in a straightline and prevent any accidental displacement of the plow regardless ofthe depth the plow may be set to run.

For the purpose of securely attaching the I converging flanged plate 5to the standard 2 the bolt 18 is provided, which bolt secures the lowerforward end of the standard to the converging flanged plate 5. The upperrear end of the converging flanged plate 5 is attached by means of thecross-bar 19 and the bolts 20. It will be understood that the apertures21 serve the dual purpose of provid ing a means for clamping the rearends of the runner members together by means of the clamping-bolt 17 andalso serves for receiving the bolt 15 when the ends of the runners havebeen interchanged.

Having fully described our invention, what we claim as new, and desireto secure by Letters Patent, is

1. A plow and a suitable standard therefor, a converging flanged platesecured thereto, a flanged block orhead secured to the lower forward andunder portion of the converging flanged plate, a runner pivotallyattached to the flange of the head or block, said runner ada ted to beinterchanged endwise, and a kni e adjustably secured between the runnermembers and a double moldboard and share secured to the convergingflanged plate, substantially as and for the purpose specified.

2. In a plow, the combination with the standard, share and moldboard, aconverging flanged plate, of a depth runner adapted to be interchangedendwise, a flanged block secured in fixed position upon the under sideof the converging flanged plate, a doubleedged knife adapted to beclamped in fixed position with reference to the runner, and means foradjusting the doubleedged knife in a horizontal plane, substantially asand for the purpose specified.

3. In a plow the combination with a standard, share and doublemoldboard, of a converging flanged plate, of a depth runner and aflanged block, said depth runner pivotally attached at its forward endto the flanged block, means for holding the runner in fixed adjustment,and means for adjusting the double-edged knife relative to the runner,substantially as and for the purpose specified.

4. A double-moldboard plow comprising a standard, a converging flangedplate secured to the standard, and a share secured to the convergingflanged plate, a flanged block secured to the converging flanged plate,a depth runner formed of sections or'members and adapted to bereversed-lengthwise, and their forward ends pivotally attached to theflange of the flanged plate, a knife adjustably attached between thesections of the runner, means for holding the runner-sections and theknife in fixed adjustment, substantially as and for the purposespecified.

5. In a plow the combination with a suitable standard, a moldboard andshare, a converging flanged plate and a flanged block secured thereto, adepth runner pivotally attached to the flange of the flanged plate, saiddepth runner adapted to be interchanged endwise, a double-edged knifeprovided with a slot intermediate its ends, a bolt located through thedepth runner and the slot of the depth runner and means for clamping thedouble-edged knife back of the rear end of said knife, substantially asand for the pur pose specified.

In testimony that we claim the above we have hereunto subscribed ournames in the presence of two witnesses.
